Rice (Oryza sativa L.) is one of the most widely grown cereals in the world and is the staple food for much of its population. Senegal, a major consumer of rice, uses the international market to cover its needs. Improving the productivity and organoleptic characteristics of grains is one of its research areas to secure this food. In this context a screening of 120 new rice lines from varietal selection with anther culture in VFS was undertaken on the basis of seven (7) characters. This study is carried out in the experimental station of ISRA Saint-Louis, in the commune of Fanaye. Its objective is to evaluate the variability existing between 4 control varieties. The design used is an "augmented design". The results obtained show that, apart from the yield, the six (6) other parameters have significantly significant differences between the controls. The comparison of them and the controls shows very interesting agronomic performances of some of them. Frequency analysis revealed that 44.16% of the lines were extra vigorous, 15% had a greater height at maturity than those that were popularized and 12.50% had a smaller height. The combination of all these variables permitted leaving of the collection 40 best varieties to be advanced in a preliminary participatory yield trial.
